In the rostral HF, there was a trend toward a negative relationship between time in the barn and PCNA expression [B = −0.0030, SEM = 0.002, F(1, 47.2) = 3.17, p = 0.082], with no relationship in the caudal HF [B = 0.0005, SEM = 0.001, F(1, 40.2) = 0.33, p = 0.570]. Here, PCNA is linked to hydrops fetalis.
